11. Maintenance instructions
This section describes how to replace the quartz glass heating element.
The removal and installation of the quartz glass heating element
!
may only be carried out by qualified personnel!
11.1 Replacing the quartz glass heating element
The long-lasting quartz glass heating element is to a
large extent maintenance and wear-free. However,
when working over a longer period at higher voltages,
abrasive substances may dirty or damage the white
insulation material of the heating element; in this case,
replacement may be required.
For safety reasons the entire quartz glass
!
heating element has to be replaced if the
quartz glass heating element (3a) becomes
damaged and cracks, chips or similar
damages are noticeable.
11.2 Removal of the the quartz glass heating element
Before removing the heating element, wait
!
until the device cooled down, then remove
the power plug (12) from the power outlet
and remove the connector (10) from the
power socket (5). Danger of electric shock!
Remove retaining screws (9) of the splash guard (7) on
the back of the device. Remove splash guard (7) and pull
out the depth stop (8) and the ceramic annealing tube (3b)
(see paragraph 6). Subsequently, remove both screws
(E1) from the casing and remove carefully (E2) the rear
panel.
Pull the heating element (3a) just a few centimetres out
of the casing. While using a suitable screwdriver, loo-
sen both screws (E4) on the power side of the ceramic
terminal (E5). Pull both black wires (E6) from the ceramic
terminal (E5). Completely remove the heating element
(3a) from the casing.
